Abstract

A switchgear device (100) is described, comprising a housing (102), an ON contact (104), a conducting rod (110), and an arc management arrangement (120) which comprises a nozzle assembly (126) arranged inside the housing. The nozzle assembly comprises a nozzle holder (128) with a base (132) having a first aperture (136) and a plurality of first gas openings (138), and a nozzle top (130) engaged inside the nozzle holder and having a second aperture (140). When the conducting rod moves from an ON position to an OFF position, the conducting rod engages and moves the nozzle assembly therewith, resulting in a gas provided in a first space (100a) of the housing getting compressed and passing through the first gas openings and a first gap (G1) between the nozzle top and the conducting rod to a second space (100b) of the housing.
